4. Turn the switch to the ON position.
5. Look into the eyepiece. Using a screwdriver (or empty cartridge case), turn the adjustment turrets
until the reticle moves into the center of the target.
NOTE:
To shift the aiming dot to the right, turn the windage adjustment screw CCW. To shift it to the
left, turn the screw CW.
To shift the aiming dot down, turn the elevation adjustment screw CCW. To shift it up, turn the
screw CW.
6. Fire a series of shots.
7. Work out the values of the elevation and windage corrections required to compensate for the mea-
sured deviation of the mean point of impact (MPI) from the center of the target. The minimum correc-
tion value of 17 SOA for Vulcan 4.5X (1/3 inch at a distance of 100 yards or 0.85cm at a distance of 100m),
12 SOA for Vulcan 6X (1/5 inch at a distance of 100 yards or 0.6cm at a distance of 100m), and 9 for Vulcan
8X (1/6 inch at a distance of 100 yards or 0.45cm at a distance of 100m) corresponds to one click of the
adjustment mechanisms.
8. Adjust the equipment boresight by turning the adjustment screws and counting out a definite num-
ber of clicks (or reading the scales).
NOTE:
To shift the MPI to the right, turn the windage adjustment screw CW. To shift the MPI to the left,
turn the screw CCW.
To shift the MPI down, turn the elevation adjustment screw CW. To shift the MPI up, turn the
screw CCW.
9. To check the equipment’s boresight, take aim at the center of the target and fire a series of shots.
10. After completing the boresight adjustment procedure, turn the device OFF and replace the caps on
the adjustment turrets.
